Abstract
Abstract A preset positioning device which is suitable for push-button tuners, and in particular for car radios. The device has a frame with a locator and a reference both mounted on the frame and both movable relative to the frame through respective ranges of corresponding positions. Means are provided for setting of the locator to a desired position. An actuator is operable either to move the reference to store a set position of the locator or to move the locator to take up a pre-set position stored by the reference.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
157 words
A preset positioning device comprising a frame, a locator mounted on the frame and movable relative to the frame through a first range of settable positions, the locator having a locator pin mounted thereon and movable therewith, a setting means for moving the locator to set its position, a reference pin mounted on the frame and movable relative to the frame through a second range of positions corresponding to the positions of the first range, and an actuator operable in a first mode to move the reference pin to store a set position of the locator pin and in a second mode to move the locator pin to take up a preset position stored by the reference pin, the actuator having a comparator with two forwardly splayed prongs and an aligning throat at the junction of the two prongs, the prongs being arranged to engage both of the said pins and cam them into the aligning throat.
Claim 2
Dependent Claim
157 words
A preset positioning device comprising a frame, a locator mounted on the frame and movable relative to the frame through a first range of settable positions, the locator having a locator pin mounted thereon and movable therewith, a setting means for moving the locator to set its position, a reference pin mounted on the frame and movable relative to the frame through a second range of positions corresponding to the positions of the first range, and an actuator operable in a first mode to move the reference pin to store a set position of the locator pin and in a second mode to move the locator pin to take up a preset position stored by the reference pin, the actuator having a comparator with two forwardly splayed prongs and an aligning throat at the junction of the two prongs, the prongs being arranged to engage both of the said pins and cam them into the aligning throat.
Claim 3
Dependent Claim
29 words
A preset positioning device according to claim 1 including a clamp for fixing the position of the reference pin except during the first mode of operation of the actuator.
Claim 4
Dependent Claim
23 words
A preset positioning device according to claim 1 wherein the reference pin and the locator pin are aligned axially in the aligning throat.
Claim 5
Dependent Claim
23 words
A preset positioning device according to claim 1 wherein the reference pin and the actuator pin are aligned radially in the aligning throat.
Claim 6
Dependent Claim
23 words
A preset positioning device according to claim 1 wherein the reference pin and the locator pin are both made of accurately dimensioned steel.
Claim 7
Dependent Claim
16 words
A preset positioning device according to claim 1 wherein the comparator is made of plastics material.
Claim 8
Dependent Claim
29 words
A preset positioning device according to claim 1 wherein the actuator is a push-button assembly disposed to move at right angles to the direction of movement of the locator.
Claim 9
Dependent Claim
47 words
A preset positioning device according to claim 1 wherein the reference pin is mounted on an arm which is rotatable about a fixed point of the frame, the resulting arc of movement of the reference pin being substantially parallel to the range of movement of the locator.
Claim 10
Dependent Claim
15 words
A push-button tuner comprising the preset positioning device of claim 1 associated with tuning means.
Claim 11
Dependent Claim
52 words
A combined push-button car radio tuner and tape player which includes the preset positioning device of claim 1 and thereby leaves sufficient space for a tape container to be introduced into the tape player through a gap between the push-buttons and the edge of the standard-sized hole provided for radios in cars.
